Giant: As a Namekian, visit Guru's house at Level 35. Speak to Piccolo, then Nail, then Dende, then Piccolo again to begin a fight that will unlock the Giant form. This form drains stamina, but makes you giant and gives unique moves. It is very powerful, but the damage inflicted to you will reflect in your stamina as opposed to your health; once stamina is depleted, the form drops and you will be left in stamina break status.

Golden: As a Frieza, complete the Frieza faction by training on Frieza's Spaceship with Zarbon, then Ginyu, then Golden Frieza, and finally Meta-Cooler to unlock the Golden form. To enter Frieza's Spaceship, reach Level 20 and give Appule a Med-Mix Capsule. The Golden form provides an increase to Ki blasts and speed, and changes the nature of standard Ki blasts. Note: Level 57 is the minimum requirement for the Golden form for the Frieza race.

Kaioken: After the Saiyan Saga, successfully complete Parallel Quest 08: "Invade Earth" to potentially unlock the Kaioken transformation. The mission requires you to defeat enemies while Nappa survives (Ultimate Finish required). You will then fight revived Goku. He will use the Kaioken transformation. Defeat him to have a chance of unlocking the Kaioken transformation. If you do not get it, keep completing the mission until you get it. It may also not unlock until you have progressed further in the game, past the Future Saga. You may also have to master the skill before it unlocks. Kaioken levels are based on your Ki levels. One energy bar is normal Kaioken, 3 bars is x3 Kaioken, and 5 bars is x20 Kaioken. This transformation will drain your stamina -- at x20 it will drain very quickly. This makes both your normal and Ki attacks stronger.

Potential Unleashed: Pass all five advancement tests with a "Z" rank to unlock an additional advancement test. Complete that advancement test to get the Potential Unleashed form. The transformation costs 5 Ki bars to use.

Power Pole Pro: As a human, progress through the Hercule faction by speaking with Saiyaman (do not worry about Hercule himself). Eventually he will offer you a quest to unlock the Power Pole Pro form. This form has long reach, recovers stamina even while moving, and allows for guarding while moving.

Purification: As a Majin, progress through the Buu faction until he has three kids to get the Purification form. This form transforms you into Kid Buu, overriding your moves and stats, while also draining stamina. It is recommended to use the Potential Unleashed form instead.

Super Saiyan ("Awoken" skill): Successfully complete some story missions and reach Level 30 to unlock an event at the Capsule Corp time rift with Vegeta. As a Saiyan, complete the sparing mission with Vegeta. Complete some more story missions until you reach Level 40 and unlock the Kid Buu battle story mission. After defeating Kid Buu, while Goku is charging his spirit bomb, there will be another event with Vegeta at Capsule Corporation. Complete the mission with Vegeta, then talk to Bulma, then Trunks, then go back to Vegeta for the final battle between Goku, Vegeta, and your character. They will then teach you the "Awoken" skill, allowing you to use Super Saiyan, Super Saiyan 2, and Super Saiyan 3.

Super Vegeta: Unlock Super Saiyan, then reach Level 60. You will get a notification about a new mission at Capsule Corporation. Go there and talk to Vegeta. You will have to defeat Super Saiyan God Vegeta to unlock the Super Vegeta 1 and Super Vegeta 2 forms.

Play as Black

At the character selection screen, press Down while scrolling through the characters to find Black. He appears after Akuma.

First, defeat Broly in Story mode. He appears a few times in the story. Complete the Buu Saga, then search for Broly. He can be found hovering around the area where you collect Parallel Quests, in between there at the World Tournament area. Fly close to Broly, and he will attack you. Defeat Broly, and you will return to Conton City. Refresh the city to make Broly available as an instructor. To refresh the city, you can either do a quick mission or just create a Parallel Quest lobby and leave to load back into the city. Note: You must be "God" rank before you can train with Broly, as he does not appear before that.

The Flying Nimbus

In Conton City, fly up just above the floating islands and search around the city (in the Namekian's area, between the Patroller's School and Mushroom area) for a flying character named "Oba". Talk to him to get The Flying Nimbus, which is one of the vehicles you can use to float around Conton City.

Throughout the game, you will have to defend Guru's House from those seeking the Dragon Balls. The more defense missions you complete, the more Guru will reward you. Successfully complete the indicated number of missions to unlock the corresponding reward:

After completing the "Warrior From The Demon World" Time Vault chapter and viewing the normal ending sequence, the story completion (under player stats) will still not display at 100%. That is because there is another secret mission called "Unknown History".
To unlock it, you must complete a series of quest lines in the five Time Rifts (the large flying objects over Conton City) to get five Distorted Time Eggs. Give the eggs to the Supreme Kai near the Time Vault, then speak to Trunks. If you cannot progress in a quest line, it is because your power level is too low or you need to wait between fights and do something else. It is recommended you are around Level 75 when attempting all of this. Successfully complete the indicated tasks to earn all five Time Eggs:

1. Hercule's House: Complete all six Sayamen quests in Hercule's House. When you enter the house area, turn right to find them in the courtyard. If they are not there, you must talk to them in the Resort District/Kame House first. You can ignore Hercule's quests, as only the Saiyamen quests matter.

2. Capsule Corporation: Complete all four Vegeta fights. He is standing in the left side of the area. If he does not offer you a fight, your level is too low and you must gain a higher level.

3. Guru's House: Defend Guru's house ten times (complete ten of Nail's quest in the House area). After accepting the first quest in this area, you will sometimes see a notification in the top right corner of the screen that the house is under attack. When this happens, Nail will offer you a new quest there. In those quests, you must collect some Dragon Balls. There are six parts to the quest. After completing all six, they reset to Part 1. You must keep doing these quests until a total of ten have been completed. Then, speak to Guru for him to power up your Shenron Wishes.

4. Majin Buu's House: Feed Buu until he has six children.

5. Frieza's Spaceship: Complete all 17 quests in Frieza's Spaceship. Some of the quests will not appear right away and you must leave. Let some time go by and complete some other fights (for example, Parallel quests). After a few other fights, you should see a notification in the top right corner that a new mission is available in the spaceship. You also need to have a higher power level before some quests become available.

"Unknown History" secret ending and True Final Boss fight walkthrough

Unlock the "Unknown History" secret mission. During the mission, you will fight as Bardock vs. Mira. Afterwards, Trunks will visit Gohan and they fight Android 17 and Android 18 to alter history for a safer future. Complete the secret mission to view the hidden ending and unlock the "Defiance In The Face Of Despair!!" achievement.

Infinite Dragon Balls

Dragon Balls are the most useful and iconic item in the game. There are seven of them in total. Once you have found all seven, Shenron can be summoned at the Dragon Ball Pedestal. He will grant you a wish. You will get the "I Summon You Forth: Shenron!" achievement for making a wish. You need to do this several times to unlock all characters in the game. Always wish for a new playable character to unlock them all and get the "I've Come For You!" achievement. Use the following method to get Dragon Balls easily:

1. Play Parallel Quest #04: "Prepare For The Attack Of Saiyans!"

2. Defeat the first three enemies as quickly as possible.

3. A portal will appear, and shortly afterwards a group of Time Patrollers will spawn. Stay in the starting area; do not go through portal yet.

4. Challenge the Time Patrollers to a fight and defeat them. Time Patrollers always drop one of three item types: materials, equipment, and key items. Look for key items, as they are always Dragon Balls. It will display the type of drop at the bottom of the screen. If you get a key item, finish the quest. If you do not get a key item, immediately restart the quest and try again.

This method allows you to get one Dragon Ball approximately every three playthroughs -- roughly one every five minutes. You should be able to farm all seven Dragon Balls within 30-60 minutes. It works online and offline.

Easy food for Majin Buu

Feeding Majin Buu at his house will make him bear children. You gain access to this area after making some progress in the story. When he has six children, he will give you a Distorted Time Egg, which is needed for the secret ending and to reach 100% completion for the story. Feeding his children can also provide some nice rewards, such as new clothing and Super Souls. Feed a child multiple times for him or her to change colors and unlock an achievement. You get food from collecting Blue Orbs in Canton City. Collect some Blue Orbs, then complete one fight for everything to respawn. Repeat this as many times as desired.

The following is a list of all wishes Shenron grants and what the wishes unlock. Note: After finishing the Guru House and seeing Guru again after getting the 125 skill points from him, you will unlock new wishes (rare item, ultimate attack, super attack, grow more, full stomach).
